You’re no psychic, but you do have an uncanny knack for predicting when your forehead will erupt. But how to get rid of the unmentionable thing remains a guessing game. No longer, now that you have the phone number of Delivering Beauty, the new at-home dermatology service run by Susan Kline (self-proclaimed face whisperer and actual physician’s assistant) and plastic surgeon Dr. Kevin Tehrani. They’ll go anywhere in the city, dispatching Kenalog (cortisone) shots (which will keep that nasty underground zit from seeing the light of day); writing emergency acne prescriptions (unlike St. Vincent’s, they won’t laugh at you); performing chemical peels; and pumping you with collagen, Restylane, and Botox (though, seriously, you look great already). Get your vanity fix without the annoying waiting rooms, rude receptionists, or inevitable blotchy postfacial run-in with the nemesis. Professional care that comes right to you — wherever, whenever. No second-guessing necessary. Delivering Beauty (212-439-9900 or deliveringbeauty.com).
